Not needing a degree doesn't mean there's no training. For example training to be a commercial airline pilot is a lot tougher that getting many degrees. I know people who have a degree and a commercial airline licence, and they said getting a degree was much less work, cost, and stress.

More than half of the displayed jobs need a degree in EU. To be honest I am glad that an educated person does things he needs to know basics about instead of just hoping the person in front of me had some experience that allowed him to do whatever he does.

It is not about that degree, that is just a piece of paper telling a person has gone throu a program. It is about a standart that has a value. A borderline where you can expect the people passing it have the basic skillset with them. It is up to each alone how good they get after that point

ALL of the power plant (gas, nuclear) operators, technicians, control room operators etc. have degrees in one form or another, many of which are engineers. Spent a large amount of time working in them, they dont just take idiots walking in off the road.
